Thinly encrusting, usually less than 0.1 cm thick, and only up to 10 cm in maximum diameter. Small oscula (≤ 2 mm) scattered on the surface, some on the top or sides of short elevations. Fragile. Colour. Deep-blue (cobalt hue if subject to strong light), with green shades, in life (Fig. 11A, B) and blue in ethanol. Skeleton. Not much distinction between ectosomal and choanosomal skeletons, as tylostyles tufts erect on the substrate, mostly fan out and pierce the surface up to 300 µm. Occasionally, one-spicule-long tracts (ca. 50 µm across) bridge the distance between substrate and the (sub)ectosomal tufts. Some tylostyles were also found parallel to the substrate. Abundant subsurface canals or lacunae (diam = 100–300 μm, Fig. 11C). Spicules. Megascleres. Tylostyles, straight or slightly curved, smooth, sharp apex, with lobate, often irregular head (100–422 x 3–11 μm, Fig. 11 D–J, Table 10). Ecology. This species was found as epibiont on gastropods ...
